I recently set up my server using Ubuntu 8.04 using webmin, but I am stuck trying to backup my data files to my NAS for additional protection.

I have it set up as follows:

Directories to backup - /mymounts/d2p1/users/xhome/xmf
Backup to - Host    as user   in file or device 
through SSH.

I get the following output:

Performing backup of /mymounts/d2p1/users/xhome/xmf to  ..

root@'s password:
bash: line 1: /usr/sbin/rmt: No such file or directory
tar: root@\:/c/backup/08_19_2010_xmf.tar: Cannot open: Input/output error
tar: Error is not recoverable: exiting now

The issue is that this is the same NAS and folder that I have successfully backed up my config files to using the same input (local network address and folder).

Anyone have some ideas that may help?
